Abstract: An aluminum alloy foil having a composition, including Fe: 1.2% by mass or more and 1.8% by mass or less, Si: 0.05% by mass or more and 0.15% by mass or less, Cu: 0.005% by mass or more and 0.10% by mass or less, and Mn: 0.01% by mass or less, with a remainder being Al and inevitable impurities. An average crystal grain size of the aluminum alloy foil is 20 to 30 ?m, a maximum crystal grain size/the average crystal grain size is ?3.0, a Cube orientation density is 5 or more, a Cu orientation density is 20 or less, and an R orientation density is 15 or less.

Abstract: The present invention discloses a personal handphone system (PHS) handset for children, which comprises a plurality of indicating lamps, a plurality of drawings corresponding to the indicating lamps, a plurality of arrow keys and an enter key for selecting the indicating lamp, a lit indicating lamp being selected by controlling the arrow keys, and a telephone number corresponding to an indicating lamp being stored in a memory of the handset, so that when a phone call is dialed from the handset by pressing the arrow keys to move the lit indicating lamp next to a drawing corresponding to the desired telephone number and pressing the enter key, a microprocessor of the handset reads the telephone number corresponding to the code of the indicating lamp from the memory and dials that telephone number directly.

Abstract: The present invention is to provide an apparatus for improving communication quality of PHS handset and method thereof, which enables any two PHS handsets to be extensions and communicate directly by utilizing a fixed private telephone or a fixed public telephone having a wireless communication exchange module as a main telephone, so that the PHS handsets are able to not only communicate directly therebetween but also make or receive a call through the connections among the fixed telephones and operate normally in an environment without having the external cell stations.

Abstract: The present invention discloses a method of sending documents from one PC to another PC via two PHS handsets in a short distance, which comprises the steps of enabling two PHS handsets to register in a group for establishing a wireless channel for communication, interconnecting a first PHS handset and a first PC by a first interface, interconnecting a second PHS handset and a second PC by a second interface, taking the first PHS handset as a main telephone and the second PHS handset as an extension respectively to establish a connection between the PHS handsets for a subsequent communication in response to calling the second PHS handset by the first PHS handset; and wirelessly sending the document from the first PC to the second PC via the PHS handsets.
